(When I say 'exact' I refer the the weak HS atop the 0; as were all the examples in my original find).

Anyway, when I first introduced the 50p chips (a box of approx. 100 pieces), I was asked "why are there only 50p chips and no other denomination from the club?" Many years had passed before the denoms you mention turned up.... and you have no idea how I looked high and low searching for the other denoms; even wrote a few articles in "Collectors' Mart" (Middlesex) which produced nothing. I always liked that chip... and I wonder if there are any w/o the weak HS.
